It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Please refer to Figure 1 , and now the battery electrode roll-up tissue paper guiding device and roll press provided by the present utility model will be described. The battery electrode roll-up tissue paper guiding device includes a frame body. An electrode feeding mechanism and an electrode roll-up mechanism 3 are respectively arranged at both ends of the workbench of the frame body. A tissue paper unwinding mechanism 1 and a tape connecting platform 2 are also arranged on the frame body; the tissue paper unwinding mechanism 1 is located on the upper side or the lower side of the workbench, and the tape connecting platform 2 is located between the tissue paper unwinding mechanism 1 and the electrode roll-up mechanism 3; the electrode of the electrode feeding mechanism and the tissue paper of the tissue paper unwinding mechanism 1 are attached on the tape connecting platform 2 and are rolled up to the electrode roll-up mechanism 3.

[0021] Compared with the prior art, for the battery electrode roll-up tissue paper guiding device provided by the present utility model, the electrode feeding mechanism conveys the electrode towards the direction of the electrode roll-up mechanism 3. The tissue paper unwinding mechanism 1 is located on the upper side or the lower side of the electrode feeding mechanism. The tissue paper in the tissue paper unwinding mechanism 1 and the electrode output from the electrode feeding mechanism move synchronously to the tape connecting platform 2, the tissue paper and the electrode are attached, the tissue paper is used as the guiding tape when the electrode enters the subsequent process, and then the attached electrode is rolled up. On the premise of meeting the process requirements, the frequency of tape breakage is reduced, and after the tape breaks, it can be timely attached to the tissue paper and continue to be rolled up, reducing material waste and improving production efficiency and product yield.

[0022] The frame body can follow the original equipment and be modified on the original frame body. A tissue paper unwinding mechanism 1 is added to the frame body and the position of the original tape connecting platform 2 is changed. The original tape connection for the electrode is changed to the attachment of the electrode and the tissue paper for tape connection. Using the tissue paper as the guiding tape, when the electrode breaks, only the end of the electrode needs to be attached to the tissue paper, and it is carried by the tissue paper to the electrode roll-up mechanism 3 and connected to the break point of the previous section of the electrode, reducing material waste in the production process.

[0023] Optionally, the electrode feeding mechanism includes a direction-changing roller 4.

[0024] In some possible embodiments, please refer to Figure 1 , a longitudinal fixed plate 8 is arranged at the upper end of the workbench, and the tissue paper unwinding mechanism 1 is rotatably arranged on the fixed plate 8.

[0025] When retrofitting on the original frame, a fixing plate 8 can be set on one side of the workbench, and the fixing plate 8 extends upward. The fixing plate 8 is fixedly connected to the frame and serves as a support structure for fixing the tissue paper unwinding mechanism 1. The connection method can be bolt connection or welding.

[0026] The tissue paper unwinding mechanism 1 includes a reel, on which the tissue paper is wound. When unwinding, the reel rotates to release the tissue paper. The tissue paper unwinding mechanism 1 can be a passive unwinding, and only rotates by the traction of the rotation of the pole piece winding mechanism 3 to release the tissue paper. When the reel of the tissue paper unwinding mechanism 1 rotates passively, one end of the reel is rotatably connected to the fixing plate 8 by means of a bearing.

[0027] The tissue paper unwinding mechanism 1 is located above the pole piece feeding mechanism. The tissue paper of the tissue paper unwinding mechanism 1 and the pole pieces of the pole piece feeding mechanism are both located on the side of the tape connecting platform 2 away from the pole piece winding mechanism 3. The tissue paper and the pole pieces move towards the tape connecting platform 2 at the same time. They are bonded on the tape connecting platform 2, and the bonded tissue paper and pole pieces move towards the side of the pole piece winding mechanism 3 at the same time until they are wound around the reel of the pole piece winding mechanism 3 to realize the winding of the pole pieces.

[0028] When the tissue paper guides the pole pieces to the pole piece winding mechanism 3, the tissue paper and the pole pieces are regarded as a whole and wound around the reel of the pole piece winding mechanism 3 to realize the winding of the pole pieces. Or the tissue paper drives the break point of the pole piece to move to fit and connect with the break point of the previous section. After the connection is completed, the tissue paper and the pole pieces are wound around the reel of the pole piece winding mechanism 3 as a whole.

[0029] In another embodiment, when the tissue paper guides the pole pieces to the pole piece winding mechanism 3, the tissue paper can drive the break point of the pole piece to move to fit and connect with the break point of the previous section. After the connection is completed, the tissue paper and the pole pieces are separated, and the tissue paper is collected separately.

[0030] In some possible embodiments, please refer to Figure 1 , the tape connecting platform 2 is arranged on the fixing plate 8, and the tape connecting platform 2 is located below the tissue paper unwinding mechanism 1 and close to the side of the pole piece winding mechanism 3.

[0031] To facilitate the bonding of the pole pieces and the tissue paper, the height of the tape connecting platform 2 is set between the tissue paper unwinding mechanism 1 and the workbench. The tape connecting platform 2 is installed on the fixing plate 8 to reduce the angle change of the conveyance of the tissue paper and the pole pieces. The tape connecting platform 2 is inclined, and the included angle range between the working surface of the tape connecting platform 2 and the horizontal plane is 15° - 45°. Preferably, the included angle between the working surface of the tape connecting platform 2 and the horizontal plane is 30°. The 30° inclination of the tape connecting platform 2 is convenient for the staff to stand at the winding position to operate the tape connection.

[0032] Correspondingly, for the convenience of the staff to operate the tape connection, the upper part of the fixed plate 8 is provided with an inclined edge, and the working surface of the tape connection platform 2 is flush with the inclined edge. This avoids the problem that the fixed plate 8 protrudes from the working surface of the tape connection platform 2, which brings inconvenience to the operation.

[0033] The fixed plate 8 is also provided with a weight-reducing hole 9.

[0034] In some other possible embodiments, there are two fixed plates 8, and the two fixed plates 8 are arranged at intervals on both sides of the workbench perpendicular to the moving direction of the pole piece; the tissue paper unwinding mechanism 1 and the tape connection platform 2 are installed between the two fixed plates 8.

[0035] The two fixed plates 8 are respectively located on both sides of the workbench. The two ends of the reel of the tissue paper unwinding mechanism 1 are respectively rotated on the two fixed plates 8, and the two sides of the tape connection platform 2 are respectively fixed on the two fixed plates 8.

[0036] The pole piece winding mechanism 3 includes a winding roller and a belt driving unit. The belt driving unit includes a driving belt pulley 6, a connecting belt 5 and a driven belt pulley 7. The driven belt pulley 7 is coaxially arranged with the winding roller. The driving belt pulley 6 is connected with a driving motor, and the driving belt pulley 6 and the driven belt pulley 7 are synchronously rotated by means of the connecting belt 5.

[0037] The winding roller is located on the workbench of the frame body and is rotatably installed at the end of the workbench. When the winding roller rotates, it drives the tissue paper to move, and then drives the material roll of the tissue paper unwinding mechanism 1 to rotate. The winding roller realizes rotation by means of the belt driving unit. Specifically, a driving motor is installed at the lower end of the workbench of the frame body, a driving belt pulley 6 is installed on the side surface of the frame body, and the driven belt pulley 7 is located below one side of the workbench; a driven belt pulley 7 is installed on the central axis of the winding roller, the driven belt pulley 7 is located above the driving belt pulley 6, and the driven belt pulley 7 and the driving belt pulley 6 are located in the same plane. The driven belt pulley 7 and the driving belt pulley 6 are connected by a connecting belt 5 to realize synchronous rotation.

[0038] A roller press is also provided, including the above-mentioned battery pole piece winding and tissue paper guiding device.
